AG Coated Glass-
Anti-Glare Glass for Displays, Touchscreens and Industrial Applications

Custom AG coated glass with controlled optical performance for applications where reflected light affects screen readability, image quality and user comfort.
Huabo supplies AG coated glass / anti-glare glass for display and industrial applications, with customization available for glass thickness, size, surface treatment, optical performance and downstream processing.
Unlike ordinary glass, an AG-treated surface is engineered to diffuse reflected light rather than produce a strong mirror-like reflection. The result is a more readable display in environments affected by overhead lighting, windows or direct ambient light.

Prevent Fingerprints Glass
Touchscreens are often plagued by fingerprints and glare. Huabo’s prevent fingerprints glass addresses both issues simultaneously. It combines AG (Anti-Glare) etching with an AF (Anti-Fingerprint)
High-definition AG Coated Glass
Many anti-glare screens make images look blurry or fuzzy. We designed our product to fix this issue. We keep the haze level very low, between 1% and 5%. This means the glass stays as clear as a
Impregnated Glass
Public touchscreens often become dirty due to fingerprints and oil. Huabo’s impregnated glass features a special coating that repels water and oil. Marks from fingers do not stick easily, and dirt
Heat Resistant Glass Sheet
Some environments are extremely demanding on standard glass. Sunlight, hot factory conditions, and medical equipment can cause ordinary screens to crack or yellow over time. Huabo’s heat resistant

Mechanism of Specular Reflection Control

A conventional glass surface is relatively smooth. When light reaches it, part of the light is reflected in a concentrated direction, creating visible glare.
AG treatment changes the surface structure so that reflected light is distributed over a wider range of directions.
Smooth Surface
→ Strong specular reflection
→ Visible Glare
Micro-Structured AG Surface
→ Diffuse reflection
→ Reduced Glare Contrast
Display
→ Less distracting reflected glare

AG glass does not mean zero reflection. Its purpose is to control the character of reflected light so that bright reflections become less visually distracting.

AG Glass Optical Performance Specification

Parameter	What It Means	Why It Matters
Gloss	Surface gloss measured at a defined angle (60°)	Lower gloss generally indicates a stronger matte / anti-glare surface
Haze	Wide-angle scattered light	Excessive haze can make images appear cloudy
Clarity	Narrow-angle visual scattering	Higher clarity helps preserve image definition
Transmittance	Visible light passing through the glass	Higher transmittance helps preserve display brightness
Surface Roughness (Ra)	Micro-texture of the AG surface	Influences light diffusion, tactile feeling and visual appearance
Sparkle	Granular visual effect on high-resolution displays	Important for monitors, touchscreens and high-PPI displays
Reflectance	Light reflected by the surface	Helps evaluate residual reflection

AGC's published AG data demonstrates why these parameters should be evaluated together rather than using a single AG level as the specification. For example, its LST range shows different combinations of Gloss, Haze, Clarity and Ra across products.

Application-Based AG Grade Selection

Application Environment	Typical Requirement	AG Selection Direction
Controlled indoor lighting	High image clarity	Light AG (Gloss 90–110 GU)
Office / commercial displays	Balanced glare and clarity	Light-to-medium AG (Gloss 70–90 GU)
Industrial HMI	Stronger ambient-light control	Medium AG (Gloss 50–70 GU)
Outdoor / high-brightness displays	Greater glare control	Medium-to-strong AG (Gloss 35–50 GU)
High-resolution display	Low visual grain / sparkle	Special low-sparkle AG
Design / professional monitors	High clarity	Fine AG surface

Surface Texture Control and Roughness

AG performance is created by controlling the microscopic structure of the glass surface. Surface roughness influences how incident light is scattered.
Technical Procurement Parameters:
▪ Ra (Average Surface Roughness)
▪ Rz (Maximum Height of Profile)
▪ Rsm (Mean Spacing of Profile Irregularities)
▪ Surface Texture Uniformity
A production target should not only define an average roughness value. It should also control uniformity across the usable glass area to avoid visible differences in:
▪ Surface Matte Visuals
▪ Glare Diffusion Level
▪ Haze Uniformity
▪ Image Sharpness

Visible Light Transmittance Performance

AG treatment should reduce distracting reflection without unnecessarily reducing display brightness.
Target Specification:
Visible Light Transmittance: ≥ 89.0%
Transmittance must be evaluated in combination with:
▪ Substrate Material
▪ Glass Thickness
▪ Haze Target
▪ Additional Functional AR Coatings

FAQ

Q: What is AG coated glass?

A: AG (anti-glare) glass features a micro-textured surface engineered to disperse specular reflection, turning bright direct reflections into soft diffuse light to improve screen readability.

Q: How does AG glass differ from AR glass?

A: AG glass scatters reflected light through controlled surface texture, while AR glass uses multi-layer optical coatings to suppress light reflection and increase transmittance. Both can be combined for specific applications.

Q: Does lower Gloss always mean better performance?

A: No. Lower Gloss increases matte diffusion but can reduce screen clarity if not matched properly. Selection should balance Gloss, Haze, and Clarity according to the viewing environment.

Q: Why is Sparkle testing necessary for high-resolution screens?

A: Micro-textures on standard AG glass can refract pixels on high-PPI displays, causing a grainy sparkle effect. Low-sparkle AG glass prevents visual noise on 4K, medical, and high-density screens.

Q: Can AG glass undergo chemical strengthening?

A: Yes. AG glass can be chemically strengthened or thermally tempered depending on the substrate type, thickness, and mechanical strength requirements.

Q: Are custom shapes, printing, and coatings supported?

A: Yes. Huabo provides custom CNC profiling, hole drilling, ceramic/organic silk printing, and integrated AR/AF surface processing.
